Question

The owner of Britten’s Egg Farm wants to estimate the mean number of eggs produced per chicken. A sample of 19 chickens shows they produced an average of 18 eggs per month with a standard deviation of 3 eggs per month. (Use t Distribution Table.)

a-1. What is the value of the population mean?

multiple choice 1

It is unknown.
18
3

a-2. What is the best estimate of this value?

c. For a 98% confidence interval, what is the value of t? (Round your answer to 3 decimal places.)

d. What is the margin of error? (Round your answer to 2 decimal places.)

e. Develop the 98% confidence interval for the population mean. (Round your answers to 2 decimal places.)

f-1. Would it be reasonable to conclude that the population mean is 18 eggs?

multiple choice 2

f-2. What about 25 eggs?

multiple choice 3

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
